Abstract

The pyrolysis and in-line catalytic cracking of a polyolefin mixture composed of 40% PP, 30% LDPE and 30% HDPE has been conducted on a HY zeolite catalyst. The plastics pyrolysis step has been performed in a conical spouted bed reactor at 500 °C in continuous mode, attaining a stream with 69.8% of waxes (>C 21 ) and 30.2 wt% of volatiles (
